kbuild: do not quote string values in include/config/auto.conf

2022-01-08T09:03:57Z

The previous commit fixed up all shell scripts to not include include/config/auto.conf. Now that include/config/auto.conf is only included by Makefiles, we can change it into a more Make-friendly form. Previously, Kconfig output string values enclosed with double-quotes (both in the .config and include/config/auto.conf): CONFIG_X="foo bar" Unlike shell, Make handles double-quotes (and single-quotes as well) verbatim. We must rip them off when used. There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X)) These are not only ugly, but also fragile. [1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar " [3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar" [4] seems to work better, but has a cost of forking a process. Anyway, quoted strings were always PITA for our Makefiles. This commit changes Kconfig to stop quoting in include/config/auto.conf. These are the string type symbols referenced in Makefiles or scripts: ACPI_CUSTOM_DSDT_FILE ARC_BUILTIN_DTB_NAME ARC_TUNE_MCPU BUILTIN_DTB_SOURCE CC_IMPLICIT_FALLTHROUGH CC_VERSION_TEXT CFG80211_EXTRA_REGDB_KEYDIR EXTRA_FIRMWARE EXTRA_FIRMWARE_DIR EXTRA_TARGETS H8300_BUILTIN_DTB INITRAMFS_SOURCE LOCALVERSION MODULE_SIG_HASH MODULE_SIG_KEY NDS32_BUILTIN_DTB NIOS2_DTB_SOURCE OPENRISC_BUILTIN_DTB SOC_CANAAN_K210_DTB_SOURCE SYSTEM_BLACKLIST_HASH_LIST SYSTEM_REVOCATION_KEYS SYSTEM_TRUSTED_KEYS TARGET_CPU UNUSED_KSYMS_WHITELIST XILINX_MICROBLAZE0_FAMILY XILINX_MICROBLAZE0_HW_VER XTENSA_VARIANT_NAME I checked them one by one, and fixed up the code where necessary.

sh: fix build error for invisible CONFIG_BUILTIN_DTB_SOURCE

2019-02-13T14:29:42Z

I fixed a similar build error in commit 1b1e4ee86e00 ("sh: fix build error for empty CONFIG_BUILTIN_DTB_SOURCE"), but it came back again. Since commit 37c8a5fafa3b ("kbuild: consolidate Devicetree dtb build rules"), the combination of CONFIG_OF_EARLY_FLATTREE=y and CONFIG_USE_BUILTIN_DTB=n results in the following build error: make[1]: *** No rule to make target 'arch/sh/boot/dts/.dtb.o', needed by 'arch/sh/boot/dts/built-in.a'. Stop. Prior to that commit, there was only one path to descend into arch/sh/boot/dts/, and arch/sh/Makefile correctly guards it with CONFIG_USE_BUILTIN_DTB: core-$(CONFIG_USE_BUILTIN_DTB) += arch/sh/boot/dts/ Now, there is another path to descend there from the top Makefile when CONFIG_OF_EARLY_FLATTREE=y. If CONFIG_USE_BUILTIN_DTB is disabled, CONFIG_BUILTIN_DTB_SOURCE is invisible instead of defined as "". Add obj-$(CONFIG_USE_BUILTIN_DTB) guard to avoid the attempt to build the non-existing file.

sh: fix build error for empty CONFIG_BUILTIN_DTB_SOURCE

2018-03-02T00:20:55Z

If CONFIG_USE_BUILTIN_DTB is enabled, but CONFIG_BUILTIN_DTB_SOURCE is empty (for example, allmodconfig), it fails to build, like this: make[2]: *** No rule to make target 'arch/sh/boot/dts/.dtb.o', needed by 'arch/sh/boot/dts/built-in.o'. Stop. Surround obj-y with ifneq ... endif. I replaced $(CONFIG_USE_BUILTIN_DTB) with 'y' since this is always the case from the following code from arch/sh/Makefile: core-$(CONFIG_USE_BUILTIN_DTB) += arch/sh/boot/dts/ Signed-off-by: Masahiro Yamada

kbuild: clean up .dtb and .dtb.S patterns from top-level Makefile

2017-11-08T17:20:24Z

We need to add "clean-files" in Makfiles to clean up DT blobs, but we often miss to do so. Since there are no source files that end with .dtb or .dtb.S, so we can clean-up those files from the top-level Makefile. Signed-off-by: Masahiro Yamada Acked-by: Arnd Bergmann Signed-off-by: Rob Herring
